Narrative:
We taxied via wolf to the outer and turned right to the northeast on the outer, but were actually northeast bound on 03L. I realized where I was and immediately cleared 21R to the west at taxiway victor. Taxiway wolf joins taxiway victor and the outer taxiway. In 1 area a massive expanse of concrete joins all 3 at 1 point. There is inadequate lighting to delineate the individual txwys. The yellow taxi lines were snow-covered, making it more difficult to identify the individual txwys. This was an inadvertent runway incursion. Upon realizing the alignment was on the runway, I took immediate action to clear it. I have never had a runway incursion before, or taxied west/O an appropriate ATC clearance.
